1 Scope p. 12

The present document is a technical report for enhanced Over-the-Air (OTA) test methods for NR FR1 Total Radiated Power (TRP) and Total Radiated Sensitivity (TRS), for NR standalone (SA) and NR non-standalone (NSA) operation mode.

In Rel-17, the TRP TRS OTA test method was just developed for a limited scope. This TR targets to define a full set of OTA test methods to cover different UE features for TRP and TRS measurement.

3.1 Terms p. 13

For the purposes of the present document, the terms given in TR 21.905 and the following apply. A term defined in the present document takes precedence over the definition of the same term, if any, in TR 21.905.

Browsing mode usage:

This mode corresponds to "data" mode, the device is tested via hand-only phantoms.

Primary mechanical mode:

The mode that is most often used for a specific user scenario. Every terminal has at least one primary mechanical mode, if multiple modes are supported, different primary mechanical modes may be applicable for different user scenarios, e.g., different primary mechanical modes for Browsing mode usage and Talk mode usage for the same UE.

Talk mode usage:

This mode corresponds to "talk" mode, the device is tested via head&hand phantoms.

Wrist-worn mode usage:

This mode corresponds to wearable device for wrist-worn mode, the device is tested via forearm phantoms.
